gluconeogenesis gluconeogenesis. the synthesis of glucose from noncarbohydrate sources, such as amino acids, propionate and glycerol. It occurs primarily in the liver and kidneys whenever the supply of carbohydrates is insufficient to meet the body's metabolic demands or in the rumen by the action of bacteria in well-fed ruminants.

Biogenesis Biogenesis is the production of new living organisms or organelles. The hypothesis of biogenesis, attributed to Louis Pasteur, states that complex living things come only from other living things, by reproduction (e.g. a spider lays eggs, which develop into spiders). That is, modern life does not arise from non-living material, which was the position held by spontaneous generation.

Principles of Biochemistry/Gluconeogenesis and Glycogenesis Glycogenesis is the process of glycogen synthesis, in which glucose molecules are added to chains of glycogen for storage. Glucose-6-phosphate is converted into glucose-1-phosphate by the action of phosphoglucomutase, passing through the obligatory intermediate glucose-1,6-bisphosphate. 2  Glucose-1-phosphate is converted into UDP-glucose by the action of the enzyme UDP-glucose phosphorylase.

Definitions &Translations Angiogenesis is the physiological process through which new blood vessels form from pre-existing vessels. This is distinct from vasculogenesis, which is the de novo formation of endothelial cells from mesoderm cell precursors.owever, it is also a fundamental step in the transition of tumors from a benign state to a malignant one, leading to the use of angiogenesis inhibitors in the treatment of cancer.

- noun, Medicine/Medical. 1. the production of ketone bodies in the body, as in diabetes mellitus or low-carbohydrate weight-loss diets. Origin of ketogenesis. 1910-1915. First recorded in 1910-15; keto- + genesis.

- Biology Prefixes and Suffixes: angio. The prefix (angio-) comes from the Greek angeion for vessel. The prefix (angio-) refers to a receptacle, vessel, shell or container. Angioblast (angio-blast) - embryonic cell that develops into blood cells and blood vessel endothelium.

Why Abiogenesis Is Impossible Abiogenesis is the theory that life can arise spontaneously from non-life molecules under proper conditions. Evidence for a large number of transitional forms to bridge the stages of this process is critical to prove the abiogenesis theory, especially during the early stages of the process.

Gluconeogenesis Gluconeogenesis is a ubiquitous process, present in plants, animals, fungi, bacteria, and other microorganisms. In vertebrates, gluconeogenesis takes place mainly in the liver and, to a lesser extent, in the cortex of the kidneys.In ruminants, this tends to be a continuous process. The final reaction of gluconeogenesis, the formation of glucose, occurs in the lumen of the endoplasmic reticulum, where glucose-6-phosphate is hydrolyzed by glucose-6-phosphatase to produce glucose and release an inorganic phosphate.

- Freebase(0.00 / 0 votes)Rate this definition: Oogenesis. Oogenesis, ovogenesis or oögenesis is the creation of an ovum. It is the female form of gametogenesis; the male equivalent is spermatogenesis. It involves the development of the various stages of the immature ovum. Oögenesis. ō-ō-jen′e-sis, n. the genesis and development of the ovum—also Oög′eny.—adj.

iatrogenesis iatrogenesis. Any injury or illness that occurs because of medical care. Some examples: chemotherapy used to treat cancer may cause nausea, vomiting, hair loss, or depressed white blood cell counts. The use of a Foley catheter for incontinence can create a urinary tract infection and urinary sepsis.

Gluconeogenesis Gluconeogenesis is a ubiquitous process, present in plants, animals, fungi, bacteria, and other microorganisms. In vertebrates, gluconeogenesis takes place mainly in the liver and, to a lesser extent, in the cortex of the kidneys.In ruminants, this tends to be a continuous process. In many other animals, the process occurs during periods of fasting, starvation, low-carbohydrate diets, or intense exercise.n humans the main gluconeogenic precursors are lactate, glycerol (which is a part of the triacylglycerol molecule), alanine and glutamine. Altogether, they account for over 90% of the overall gluconeogenesis.

Gene expression profiling in cancer Oncogenesis is the process by which normal cells acquire the properties of cancer cells leading to the formation of a cancer or tumor (see: tumorigenesis). It is characterized by a molecular reprogramming of a cell to undergo uninhibited cell division, allowing the formation of a malignant mass.

Angiogenesis and Angiogenesis Inhibitors to Treat Cancer Angiogenesis and Angiogenesis Inhibitors to Treat Cancer. Angiogenesis is the formation of new blood vessels. This process is a normal part of growth and healing. It is also plays a role in several diseases, including cancer. Once a tumor grows to a certain size, it needs nutrients and oxygen from the blood to grow and spread.

- When it has reached 1 to 2mm across, it needs to grow its own blood vessels so that it can continue to get bigger. The growth of new blood vessels is called angiogenesis. Anti angiogenic drugs are biological therapies that stop tumours from growing their own blood vessels. This is a quite a new way of treating cancers. Researchers are still learning how best to use these treatments.

What is gametogenesis? Gametogenesis is a process by which diploid or haploid precursor cells undergo cell division and differentiation to form mature haploid gametes.n most animals the ovaries produce the female gametes (ova) and the testicles the male gametes (sperm). it is where the female sex cells are made. The process by which haploid (or diploid in some organisms) precursor gametes become mature gametes.

Cancer Prevention Overview (PDQÂ®)âPatient Version Carcinogenesis is the series of steps that take place as a normal cell becomes a cancer cell. Cells are the smallest units of the body and they make up the body’s tissues. Each cell contains genes that guide the way the body grows, develops, and repairs itself.

- The modern definition of abiogenesis, however, is concerned with the formation of the simplest forms of life from primordial chemicals, rather than the old Aristotelian concept of abiogenesis, which postulated the formation of fully-formed complex organisms by spontaneous generation.

gluconeogenesis the synthesis of glucose from noncarbohydrate sources, such as amino acids and glycerol. It occurs primarily in the liver and kidneys whenever the supply of carbohydrates is insufficient to meet the body's energy needs. Gluconeogenesis is stimulated by cortisol and other glucocorticoids and by the thyroid hormone thyroxine.
